Magnetic resonance imaging features of nasopharyngeal carcinoma and nasopharyngeal non-Hodgkin's lymphoma: Are there differences?

European Journal of Radiology, 05/17/2012

Nasopharyngeal carcinoma (NPC) more often involved an unsymmetrical tumour with a propensity to invade both widely and deeply into muscle tissue, the fat space, the neural foramen, and the skull base bone. In contrast, nasopharyngeal non–Hodgkin's lymphoma (NPNHL) tended to be a symmetrical and diffuse tumour with a propensity to spread laterally through the fat space and along the mucosa to the tonsils of the oropharynx and hypopharynx. These differences facilitate a differentiation of these diseases using MR images, and enhance the understanding of the biological behavior of these malignant tumours of the nasopharynx.
